SPECIFICATION forming` part of Letters Patent N o. 701,952, datedfJ' une 10, 1902. Application filed March 13, 1902. Serial No. 98 ,05 5. (No model.)

T all whom, i may concern,.-

Be it known that I, CHARLES C.VSMITH, a citizen of the UnitedStates, residing at Bellevue, in the county of Blaine and State of Idaho, have invented certain new and useful Improvements inNut-Wrenches; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to nut-wrenches of the tong type, designed for use in places which are inaccessible for -wrenches of the slidingjaw type and constructed with a view of gripping and securely retaining nutsof all shapes, such as square, hexagonal, octagonal, or, in fact, any polygonal nut.

The object of the invention is to provide a wrench of this character which shall be simple of construction, durable in use, comparativelyinexpensive of production, and etlcient in action and one in which the gripping-shoes may be removed when worn and 'replaced with new ones.

With this and other objects in view the invention consis'tsof certain novelV features of construction, combinatiomfand arrangement of parts, which will be hereinafter more particularly described, and pointed outl iny ing of the lower shoe inwardly the end wall the appended claim.

In the accompanying drawings, Figure l is a view of the wrench, showing the jaws closed. Fig. 2 is a cross-sectional view on line m oc l through the upper jaw and removable grip- In the accompanying drawings, l and 2 de-l note the'handles of the levers, the outer ends of which are recessedor notched and pivoted together by a pivot 3. The outer end of the jaw 4the side of which for a ,portion off-its length beginningat the extreme outer end of the jaw is'beveled to form dovetail ribs 5,

'outer end of thellower jaw, and thus prevent which as they approach the inner or rear end of the jaw gradually merge into thev surface ofthejaw. j

6 denotes'a gripping-shoe which has on its upper surface adovetail slot 7, which is narrower at its outer end than at. itsI inner end and has at its inner end a dovetailgroove, which in the assembling or connection of the shoe with thev jaw is adapted to straddle the shank of the jaw, so that the groove may engage the lower cdgeoi` the jaw, and by sliding the shoe outwardly it will be made to firmly bind in its connection with the jaw as the narrower part of the groove is moved 'toward the wider part of the jaw.

` 10 denotes the lower jaw, formed at the outer end of the handle 2' and provided with dovetail anges 11,1which fit the ydovetail `groove of the'removable shoe 12, which is provided with a notch or slot 13 in its inner end to :receive the shank of the jaw 4 when the jaws are compressed. f In operation; assuming the jaws to be y,clamped about a nut, in the depression of the of the groove will abut against the extreme 8o further movement of said shoe, Vand the upper shoe will be forced outwardly, thus firmly binding -it to the jaw, for the farther the upper shoe is forced outwardly the tighter the engagement it will have with itsf jaw. 8 5 From the foregoing'description, taken in connection with the accompanying drawings,
